[0054] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 , shows a schematic diagram of an atomization device provided in some embodiments of the present application, the atomization device includes an atomizer 1 and a power supply component 2, the atomizer 1 is arranged on the power supply component 2 and is electrically connected to the power supply component 2, the power supply component 2 supplies power to the atomizer 1, so that the atomizer 1 performs an atomization operation.

[0055] In some examples, the power supply assembly 2 may include a housing 21 and a battery 24 . The battery 24 and the atomizer 1 are installed in a cavity formed by the housing 21 . The power supply assembly 2 may supply power to the atomizer 1 through the battery 24 .

[0056] In some examples, a switch button 22 is provided on a surface of the housing 21 of the power supply component 2 that faces the outside of the cavity, and the user can operate the switch button 22 to control the on or off.

[0057] In some examples, the power supply assembly 2 may further include a bottom cover 23 . The bottom cover 23 may be disposed on a side away from the atomizer 1 , and the bottom cover 23 is movably connected to the housing 21 .

[0058] The following combination Figures 2 to 11 The atomizer 1 in some embodiments of the present application is further described as follows:

[0059] The atomizer 1 may include a housing assembly 10 , an atomization assembly 20 , and a bottom cover assembly 30 .

[0060] like Figure 2 , Figure 3 A liquid storage chamber 110 is formed inside the shell component 10, and the liquid storage chamber 110 can be used to store an atomization matrix. The atomization matrix is ​​in liquid form, such as oil, and the atomization matrix can carry different smells. The atomization matrix can be heated by the atomization component 20 to perform an atomization operation, thereby generating an aerosol, and the generated aerosol is discharged through the shell component 10.

[0061] In some examples, in order to meet regulatory requirements in different regions, the content of the aerosolized matrix stored in the liquid storage chamber 110 can be 1 to 4 ml, specifically 1 ml, 2 ml, 3 ml, 3.5 ml and 4 ml, etc., which are not specifically limited here.

[0062] In some examples, the material of the housing assembly 10 can be selected from any one of hard resin, metal and its alloy, glass, ceramic and synthetic material, which is not specifically limited here.

[0063] like Figure 2 , Figure 3 The atomizer assembly 20 is disposed in the liquid storage chamber 110 , and the atomizer assembly 20 may include an atomizer seat 210 and an atomizer core 220 . The atomizer seat 210 is provided with a connected atomizer channel 211 and a liquid inlet hole 2121 . The atomizer core 220 is located in the atomizer channel 211 and covers the liquid inlet hole 2121 .

[0064] During the atomization operation, the atomization channel 211 and the liquid storage chamber 110 can be connected through the liquid inlet hole 2121, and the atomization matrix in the liquid storage chamber 110 can enter the atomization channel 211 through the liquid inlet hole 2121. The atomization core 220 in the atomization channel 211 can then perform an atomization operation on the atomization matrix entering the atomization channel 211, and the aerosol generated by the atomization operation is discharged through the atomization channel 211.

[0065] In some examples, the atomization core 220 may include a liquid guiding member and a heating net. The heating net may be disposed on one side of the liquid guiding member, and the other side of the liquid guiding member covers the liquid inlet hole 2121. The area of ​​the liquid guiding member is larger than the area of ​​the liquid inlet hole 2121. The atomization matrix enters the liquid guiding member through the liquid inlet hole 2121, and the atomization matrix in the liquid guiding member is atomized by the heating net to generate an aerosol.

[0066] In some examples, the liquid-conducting member is liquid-conducting cotton, and the material of the liquid-conducting cotton is selected from any one of cotton and non-woven fabric, such as sponge, cotton, artificial cotton, non-woven fabric, etc.

[0067] In some examples, one or more liquid inlet holes 2121 may be provided. By providing multiple liquid inlet holes 2121 , the speed at which the atomized substrate enters the atomization channel may be increased.

[0068] The bottom cover assembly 30 is movably connected to one end of the shell assembly 10. The bottom cover assembly 30 can move relative to the shell assembly 10. For example, under the action of an external force, the shell assembly 10 can move toward the bottom cover assembly 30. The bottom cover assembly 30 has a first position and a second position when moving relative to the shell assembly 10. The second position is a position closer to the atomizer assembly 20 than the first position.

[0069] In the non-operating state, when the bottom cover assembly 30 is in the first position, as shown in FIG. Figure 4 The bottom cover assembly 30 and the atomizer seat 210 are spaced apart, that is, the bottom cover assembly 30 and the atomizer seat 210 are not in contact with each other, and the liquid inlet hole 2121 is blocked by the shell assembly 10 to block the communication between the liquid storage chamber 110 and the atomization channel 211. The atomization matrix in the liquid storage chamber 110 cannot enter the atomization channel 211, and the atomization core 220 cannot perform atomization operation.

[0070] When the user wants to use the atomizer 1 for atomization, the user presses the shell assembly 10 toward the side close to the bottom cover assembly 30. Since the bottom cover assembly 30 and the shell assembly 10 are movably connected, when the bottom cover assembly 30 is switched to the second position, Figure 6 , the bottom cover assembly 30 first moves a distance to contact the atomizer seat 210, so that the local structure in the bottom cover assembly 30 is pressed against the bottom of the atomizer seat 210; then continue to press the shell assembly 10, the bottom cover assembly 30 pushes the atomizer seat 210 relative to the shell assembly 10, so that the liquid inlet hole 2121 is connected with the liquid storage chamber 110 to connect the liquid storage chamber 110 with the atomization channel 211, at this time, the liquid inlet hole 2121 is no longer blocked by the shell assembly 10, the liquid storage chamber 110 and the atomization channel 211 are then connected through the liquid inlet hole 2121, the atomization matrix in the liquid storage chamber 110 enters the atomization channel 211, and the atomization core 220 then uses the atomization matrix entering the atomization channel 211 to perform atomization operations. In other operating methods, the user can also achieve the displacement of the bottom cover assembly 30 relative to the shell assembly 10 by rotating the bottom cover assembly 30, etc., which is not specifically limited here.

[0071] In the embodiment of the present application, the bottom cover assembly 30 is movably connected to one end of the shell assembly 10, and the bottom cover assembly 30 moves relative to the shell assembly 10, and has a first position and a second position; and when the bottom cover assembly 30 is in the first position, the bottom cover assembly 30 and the atomizer seat 210 are spaced apart, and the liquid inlet hole 2121 is blocked by the shell assembly 10 to block the communication between the liquid storage chamber 110 and the atomization channel 211; when the bottom cover assembly 30 is switched to the second position, the bottom cover assembly 30 pushes the atomizer seat 210 to move relative to the shell assembly 10, so that the liquid inlet hole 2121 is connected to the liquid storage chamber 110, and the atomization channel 211 is connected to the liquid storage chamber 110. 10 is connected to connect the liquid storage chamber 110 and the atomization channel 211; such a configuration not only realizes the separation of the atomization matrix and the atomization core 220 in the liquid storage chamber 110 in the non-operating state, thereby reducing the oil leakage problem, but also realizes that the atomizer 1 is in an unactivated state, that is, the bottom cover assembly 30 is in the first position, and a safe distance is maintained between the bottom cover assembly 30 and the atomization seat 210. During transportation, even if the bottom cover assembly 30 is subjected to a severe collision, the atomizer 1 will not be easily activated, thereby further preventing the occurrence of oil leakage problems and greatly improving the user experience.

[0072] like Figure 7 The atomizer seat 210 may include a side wall portion 212 and a base portion 213, the atomizer channel 211 is formed inside the side wall portion 212, the liquid inlet hole 2121 is arranged on the peripheral side of the side wall portion 212, and the base portion 213 is arranged on the side of the side wall portion 212 close to the bottom cover assembly 30. Fig. 9 The bottom cover assembly 30 may include a push portion 311 , and the push portion 311 is disposed opposite to the base portion 213 .

[0073] In the non-operating state, when the bottom cover assembly 30 is in the first position, the push portion 311 is spaced apart from the base portion 213, that is, the push portion 311 is not in direct contact with the base portion 213. With the action of external force, the bottom cover assembly 30 continuously moves relative to the shell assembly 10. The bottom cover assembly 30 switches to the second position, and the push portion 311 abuts against the base portion 213 to push the atomizer seat 210 to move relative to the shell assembly 10.

[0074] Since the push portion 311 in the bottom cover assembly 30 and the base portion 213 in the atomizer seat 210 are arranged relative to each other, under the action of external force, the bottom cover assembly 30 including the push portion 311 and the atomizer seat 210 including the base portion 213 move relatively. When the push portion 311 moves to the second position, the push portion 311 abuts against the base portion 213. The push portion 311 pushes the base portion 213, thereby pushing the atomizer seat 210 to move relative to the shell assembly 10 until the liquid inlet hole 2121 is no longer blocked by the shell assembly 10, the liquid storage chamber 110 is connected to the atomization channel 211, and the atomized matrix in the liquid storage chamber 110 enters the atomization channel 211.

[0075] In some examples, the number of the pushing portion 311 may be one or more.

[0076] In some examples, a support portion (not shown) may be provided on one side of the sidewall portion 212 of the atomizer seat 20 facing the atomization channel 211 , and the support portion may be used to support the atomization core 220 in the atomization channel 211 .

[0077] In some examples, the side wall portion 212 of the atomizer seat 20 forms a cylindrical atomization channel.

[0078] In some examples, the base portion 213 of the atomizer seat 20 may be disposed at a position at the bottom 313 of the side wall portion 212 close to the bottom cover assembly 30 .

[0079] like Fig.10 The base portion 213 is protruded from the outer peripheral side of the side wall portion 212, and a limiting groove 2131 is provided on the side of the base portion 213 facing the push portion 311. The shape of the push portion 311 can be adapted to the size of the limiting groove 2131. Since the base portion 213 is provided with a limiting groove 2131 on the side of the push portion 311, when the bottom cover assembly 30 is in the second position, the push portion 311 is inserted into the limiting groove 2131, and the push portion 311 abuts against the groove wall of the limiting groove 2131 to achieve a pushing effect.

[0080] like Figure 5 The atomizer core 220 has a conductive wire 221, one end of the conductive wire 221 extends into the limiting groove 2131, and the push portion 311 can be provided with an electrode assembly 3111; the bottom cover assembly 30 moves relative to the shell assembly 10 and also has a third position, and the third position is located between the first position and the second position.

[0081] When the bottom cover assembly 30 is in the first position, Figure 4 Since the push portion 311 and the base portion 213 are spaced apart, the electrode assembly 3111 on the push portion 311 is not inserted into the limiting groove 2131 of the base portion 213, the conductive wire 221 and the electrode assembly 3111 are separated, no current flows to the atomizer core 220, and the atomizer core 220 cannot perform atomization operation.

[0082] The bottom cover assembly 30 switches from the first position to the third position, as shown in FIG. Figure 5 The electrode assembly 3111 is received in the limiting groove 2131, and the electrode assembly 3111 contacts the conductive wire 221 to form an electrical connection. The current in the power supply assembly 2 then flows to the atomizer core 220 through the electrode assembly 3111 and the conductive wire 221, and the atomizer core 220 can then perform atomization operation.

[0083] It should be noted that after the bottom cover assembly 30 is switched from the first position to the third position, the bottom cover assembly 30 is switched from the third position to the second position, and the electrode assembly 3111 is in contact with the conductive wire 221 to form an electrical connection.

[0084] In some examples, the heating net in the atomization core 220 is connected to the conductive wire 221, and the heating net heats the atomization matrix under the action of the electric current, thereby generating an atomization operation.

[0085] In some examples, the conductive wire 221 in the atomizer core 220 may be one or more conductive wires.

[0086] In some examples, the electrode assembly 3111 is adapted to the shape of the limiting groove 2131, such as a column.

[0087] In the embodiment of the present application, when the bottom cover assembly 30 is in the first position, since the push portion 311 in the bottom cover assembly 30 and the base portion 213 in the atomizer seat 210 are spaced apart, the electrode assembly 3111 on the push portion 311 is not inserted into the limiting groove 2131 in the base portion 213, and the conductive wire 221 and the electrode assembly 3111 in the limiting groove 2131 are in a separated state. Under the action of external force, the bottom cover assembly 30 moves relative to the shell assembly 10, and the bottom cover assembly 30 switches from the first position to the third position, and the electrode assembly 3111 is accommodated in the limiting groove 2131, and the electrode assembly 3111 then contacts the conductive wire 221 in the limiting groove 2131 to form an electrical connection, so that the conductive wire 221 in the atomizer core 220 is separated from the electrode assembly 3111 in the non-operating state, thereby preventing the atomizer core 220 from being accidentally triggered and causing dry burning when the atomizer matrix in the liquid storage chamber 110 and the atomizer core 220 are separated.

[0088] like Figure 2 , Figure 3 The bottom cover assembly 30 includes a bottom shell member 310, and the housing assembly 10 includes an outer shell member 120 and a sealing member 130; the outer shell member 120 has a first end and a second end opposite to each other. In some examples, the first end is an end close to the bottom cover assembly 30, and the second end is an end away from the bottom cover assembly 30.

[0089] like Figure 2 , Figure 3 The outer shell 120 has an air outlet 121, which is arranged on the first end of the outer shell 120. The atomizer seat 210 extends from the first end of the outer shell 120 toward the second end of the outer shell 120. One end of the atomizer seat 210 away from the base portion 213 is movably connected to the air outlet 121. The bottom shell 310 is movably connected to the second end of the outer shell 120. The sealing member 130 is sealingly sleeved between the outer shell 120 and the atomizer seat 210 to form a liquid storage chamber 110 between the outer shell 120, the air outlet 121, the atomizer seat 210 and the sealing member 130.

[0090] When the bottom shell 310 moves relative to the outer shell 120 , the push portion 311 cooperates with the base portion 213 to drive the atomizer seat 210 to move relative to the sealing member 130 , so that the sealing member 130 blocks or opens the liquid inlet hole 2121 .

[0091] In some examples, the air outlet 121 is embedded in one end of the atomizer seat 210 away from the base 213 , and the cavity of the air outlet 121 is connected to the atomization channel 211 of the atomizer seat 210 , thereby guiding the aerosol generated by the atomization operation in the atomization channel 211 out.

[0092] In some examples, a guide surface is provided on the side of the seal 130 close to the liquid storage chamber 110, and the guide surface is inclined toward the side of the liquid inlet hole 2121. The liquid storage chamber 110 can be composed of two parts, one part is the cavity between the guide surface of the seal 130, the inner surface of the outer shell 120, and the outer surface of the atomizer seat 210, and the other part is the cavity between the inner surface of the outer shell 120 and the outer surface of the air outlet 121.

[0093] Under the action of external force, the push portion 311 in the bottom cover assembly 30 and the base portion 213 in the atomizer seat 210 contact each other, and the push portion 311 pushes the base portion 213, thereby pushing the entire atomizer seat 210 to move toward the side away from the bottom cover assembly 30. Since the outer shell 120 limits the surrounding side of the sealing member 130, the sealing member 130 is fixed relative to the outer shell 120, and the atomizer seat 210 moves relative to the sealing member 130.

[0094] When the bottom cover assembly 30 is in the first position, the sealing member 130 in the shell assembly 10 blocks the liquid inlet hole 2121 on the atomizer seat 210. As the bottom cover assembly 30 moves, the atomizer seat 210 moves relative to the sealing member 130. When the bottom cover assembly 30 moves to the second position, the liquid inlet hole 2121 is opened, and the atomized matrix in the liquid storage chamber 110 then enters the atomization channel 211 through the liquid inlet hole 2121.

[0095] like Fig. 9 A mounting groove 314 is provided on the side of the bottom shell 310 facing the atomizer seat 210. The bottom shell 310 has a peripheral wall portion 312 and a bottom 313. The peripheral wall portion 312 of the bottom shell 310 is located at one end facing the atomizer seat 210, and the bottom 313 of the bottom shell 310 is located at one end away from the atomizer seat 210. The peripheral wall portion 312 and the bottom 313 enclose a mounting groove 314, and the mounting groove 314 opens toward one side of the atomizer seat 210.

[0096] like Fig. 9The push portion 311 protrudes from the bottom 313 into the mounting groove 314, and can then abut against the base portion 213 of the atomizer seat 210. The length of the push portion 311 can be less than the depth of the mounting groove 314. The mounting groove 314 can collect condensed substances flowing out of the atomization channel 211 (such as condensed liquid condensed between air and the tube wall of the atomizer seat, or atomized matrix that has not been atomized). Furthermore, a liquid absorbent component (not shown in the figure) is disposed in the mounting groove 314, and the liquid absorbent component can absorb the condensed substances.

[0097] like Fig.11 A positioning portion 3121 is provided on one side of the peripheral wall portion 312 facing the outer shell 120. If the positioning portion 3121 is a positioning block, the outer shell portion is provided with a first positioning hole 122 and a second positioning hole 123. The first positioning hole 122 is provided corresponding to the first position, and the second positioning hole 123 is provided corresponding to the second position. The first positioning hole 122 is closer to the bottom cover assembly 30 than the second positioning hole 123.

[0098] Among them, the positioning portion 3121 is snap-connected with the first positioning hole 122 or the second positioning hole 123. When the bottom cover assembly 30 moves to the first position, the positioning portion 3121 is snap-connected with the first positioning hole 122. When the bottom cover assembly 30 moves to the second position, the positioning portion 3121 is snap-connected with the second positioning hole 123.

[0099] like Figure 3 The bottom shell 310 is provided with a guide column 315, and the guide column 315 is embedded in the bottom 313 of the mounting groove 314. The length of the guide column 315 is greater than the depth of the mounting groove 314, that is, the guide column 315 extends out of the mounting groove 314. The guide column 315 and the positioning portion 3121 are an integrally formed structure. The sealing member 130 is provided with a guide hole 131, and the guide column 315 is slidably inserted into the guide hole 131.

[0100] Since the guide column 315 and the guide hole 131 are provided, the guide column 315 and the positioning portion 3121 are an integrally formed structure. When the bottom cover assembly 30 moves relative to the atomizer seat 210, the bottom cover assembly 30 can be guided to move along the direction formed by the guide column 315 and the guide hole 131. Then, when the bottom cover assembly 30 is in the first position, the positioning portion 3121 can be snap-connected to the first positioning hole 122. When it moves to the second position along the direction formed by the guide column 315 and the guide hole 131, the positioning portion 3121 can be snap-connected to the second positioning hole 123.

[0101] In some examples, there may be multiple guide pillars 315 , such as two, and the number of guide holes 131 in the seal 130 may be the same as the number of guide pillars 315 .

[0102] like Fig. 9The outer peripheral side of the peripheral wall portion 312 of the bottom cover assembly 30 is provided with a guide portion 3122 protruding outward, and the guide portion 3122 is a long strip. Figure 2 A guide groove 124 is provided on one side of the outer shell 120 facing the peripheral wall portion 312 . The shape of the guide groove 124 can be matched with the shape of the guide portion 3122 , and the guide portion 3122 is slidably connected in the guide groove 124 .

[0103] When the bottom cover assembly 30 and the atomizer seat 210 move relative to each other, since the guide portion 3122 in the bottom cover assembly 30 is connected to the guide groove 124 of the outer shell 120, the movement of the bottom cover assembly 30 can be more stable without deviation, so that the push portion 311 in the bottom cover assembly 30 can contact the base portion 213 in the atomizer seat 210 after movement and push the atomizer seat 210 including the base portion 213.

[0104] like Fig.10 The bottom cover assembly 30 also has an air intake passage 316 on the bottom shell 310. Figure 7 The side wall portion 212 of the base portion 213 of the atomizer seat 210 is provided with an air inlet hole 2122 , and the air inlet channel 316 , the air inlet hole 2122 , the atomizing channel 211 , and the air outlet portion 121 are connected in sequence.

[0105] During the atomization operation, the gas can enter the atomizer 1 through the air inlet channel 316 of the bottom cover assembly 30, enter the atomizer assembly 20 through the air inlet hole 2122, and undergo atomization operation with the atomizer matrix in the atomizer core 220 of the atomizer assembly 20. The aerosol generated by the atomization operation enters the air outlet 121 in the housing assembly 10 through the atomizer channel 211 in the atomizer seat 210, and is then guided out from the air outlet 121. Moreover, by changing the air inlet hole 2122 from the bottom 313 to the side, the risk of the air inlet hole 2122 being blocked by condensed matter collected by the mounting groove 314 is reduced, the normal use of the atomizer is guaranteed, and the oil collecting function is improved.

[0106] like Figure 8 A ventilation groove 2123 is also provided on the outer surface of the side wall portion 212 of the atomizer seat 210. The ventilation groove 2123 is located in the area between the liquid inlet hole 2121 and the base portion 213. One end of the ventilation groove 2123 is connected to the liquid inlet hole 2121, and the other end of the ventilation groove 2123 is bent and extended from the liquid inlet hole 2121 toward the base portion 213. When the bottom shell 310 is in the second position, one end of the ventilation groove 2123 is connected to the liquid storage chamber 110 through the liquid inlet hole 2121, and the other end of the ventilation groove 2123 is connected to the air inlet channel 316.

[0107] Since the atomization operation requires the user to start by pressing the shell, different pressing forces during the pressing process will cause different instantaneous pressures inside the liquid storage chamber 110. The pressure inside the liquid storage chamber 110 is difficult to release and may cause the atomization mechanism to overflow from the atomization core 220 and other undesirable phenomena. By setting the ventilation groove 2123 to a curved structure, effective ventilation can be achieved and the pressure can be relieved when the instantaneous pressure inside the liquid storage chamber 110 is high.

[0108] like Figure 2 , Figure 3 The bottom cover assembly 30 includes a bottom shell member 310, and the housing assembly 10 includes an outer shell member 120. The bottom shell member 310 is installed at one end of the outer shell member 120. Fig. 9 The peripheral wall portion 312 of the bottom shell member 310 can be inserted into the cavity of the outer shell member 120 , and the bottom 313 of the bottom shell member 310 is limited to the outside of the cavity of the outer shell member 120 .

[0109] like Fig.10 The atomizer 1 further comprises a circuit board 40, such as Figure 4 , Figure 5 , Figure 6 The atomizer 1 also includes an airflow sensor 50 (also called a microphone), which is arranged on the circuit board 40. A mounting structure 318 is formed on the side of the bottom shell 310 facing away from the outer shell 120, and the circuit board 40 and the airflow sensor 50 are mounted on the mounting structure 318.

[0110] The electrode assembly 3111 is penetrated through the bottom shell 310 and electrically connected to the circuit board 40. The circuit board 40 is electrically connected to the power supply assembly 2. The power supply assembly 2 can then supply power to the electrode assembly 3111 through the circuit board 40. When the electrode assembly 3111 contacts the conductive wire 221 in the atomizer core 220, the current flows to the atomizer core 220 through the conductive wire 221, and then atomization operation can be performed.

[0111] like Fig. 9 A detection air passage 317 is formed on one side of the bottom shell 310 facing the outer shell 120. The atomization channel 211 is connected to the air flow sensor 50 through the detection air passage 317. When the user inhales through the air outlet, the air enters the air flow sensor 50 through the detection air passage 317, and generates a certain pressure on the diaphragm of the air flow sensor 50. The air flow sensor 50 can detect the air flow pressure, and then control the atomization core 220 to start or stop the atomization operation.

[0112] In some examples, the airflow sensor 50 can perform detection according to a preset time, such as 3 seconds to 25 seconds, such as 25 seconds, 20 seconds, 16 seconds, 15 seconds, 10 seconds, 5 seconds, 3 seconds, etc. By setting the time interval for detection, the power of the atomizer device can be saved.

[0113] The following is an exemplary description of the operation process of the atomization device in this application:

[0114] 1. In the non-operating state, the bottom cover assembly 30 is in the first position, the push portion 311 in the bottom cover assembly 30 and the base portion 213 of the atomizer seat 210 in the atomizer assembly 20 are spaced apart, and the electrode assembly 3111 on the push portion 311 is not inserted into the limiting groove 2131 of the base portion 213.

[0115] At this time, the seal 130 in the shell assembly 10 blocks the liquid inlet hole 2121 of the atomizer seat 210, blocking the connection between the liquid storage chamber 110 and the atomization channel 211 in the atomizer seat 210, thereby realizing the separation of the atomization matrix and the atomization core 220 in the liquid storage chamber 110 in the non-operating state, that is, "oil core separation", reducing the oil leakage problem, and maintaining a safe distance between the bottom cover assembly 30 and the atomizer seat 210. During transportation, even if the bottom cover assembly 30 is subjected to a severe collision, the atomizer 1 will not be easily activated, thereby further preventing the occurrence of oil leakage problems and greatly improving the user experience.

[0116] Moreover, the electrode assembly 3111 on the push portion 311 is not inserted into the limiting groove 2131 of the base portion 213, the conductive wire 221 in the atomizer core is separated from the electrode assembly 3111, no current flows to the atomizer core 220, and the atomizer core 220 cannot perform atomization operation, thereby preventing the atomizer core 220 from being accidentally triggered and causing dry burning when the atomizer matrix in the liquid storage chamber 110 is separated from the atomizer core 220, that is, "oil-electricity separation".

[0117] 2. When the user wants to use the atomizing device for atomization, the user presses the shell assembly 10 toward the side close to the bottom cover assembly 30. Since the bottom cover assembly 30 and the shell assembly 10 are movably connected, under the action of external force, the bottom cover assembly 30 switches to the third position.

[0118] At this time, the electrode assembly 3111 on the push portion 311 is inserted into the limiting groove 2131 in the base portion 213, and the electrode assembly 3111 then contacts the conductive wire 221 in the limiting groove 2131 to form an electrical connection. The current of the battery 24 in the power supply assembly 2 flows to the atomizer core 220 via the electrode assembly 3111 and the conductive wire 221, and the atomizer core 220 is powered, so that the atomizer core 220 is capable of performing atomization operations.

[0119] However, although the atomizer core 220 is powered and has the ability to perform atomization, the seal 130 in the shell assembly 10 still blocks the liquid inlet hole 2121 of the atomizer seat 210, and the connection between the liquid storage chamber 110 and the atomization channel 211 in the atomizer seat 210 is still blocked. The atomization matrix in the liquid storage chamber 110 is atomized into the atomization channel 211, and the atomizer core 220 cannot perform atomization.

[0120] 3. As the user continues to press the shell assembly 10 toward the side close to the bottom cover assembly 30, the bottom cover assembly 30 gradually switches from the third position to the second position. When the bottom cover assembly 30 switches to the second position, the push portion 311 in the bottom cover assembly 30 abuts against the base portion 213 in the atomizer seat 210, thereby pushing the atomizer seat 210 to move relative to the shell assembly 10.

[0121] As the atomizer seat 210 moves relative to the shell assembly 10, the liquid inlet hole 2121 in the atomizer seat 210 is no longer blocked by the shell assembly 10, that is, the sealing member 130 opens the liquid inlet hole 2121, the liquid storage chamber 110 is connected with the atomization channel 211, the atomization matrix in the liquid storage chamber 110 enters the atomization channel 211, and the atomization core 220 then uses the atomization matrix entering the atomization channel 211 to perform atomization operation.

[0122] The aerosol generated by the atomization operation enters the air outlet portion 121 in the housing assembly 10 through the atomization channel 211 in the atomization seat 210 , and is then discharged from the air outlet portion 121 .
